"Before leaving Dresden for Poland, last Year (1756), he, Menzel, had returned the said key to Plessmann; who gave him others for use here. After his arrival here, he returned these keys to Benoit, in the presence of Erfurth; saying, they were of no use to him, and that he could not get at the Despatches here. Prisoner farther declares, that it was the Minister von Mahlzahn who, of his own accord, and quite at the beginning, made the proposal concerning the keys; and when Plessmann brought the keys, he said expressly they were for the Minister, along with fifty thalers, which he, Menzel, received at the same time. ACTUM UT SUPRA." Signed as before. [--Helden-Geschichte,--v. 677 (as BEYLAGE or Appendix to the Kur-Sachsen "PRO MEMORIA to the Reich's Diet;" of date, Regensburg, 31st January, 1758).] We could give some of the stolen Pieces, too; but they are of abstruse tenor, and would be mere enigmas to readers here. Enough that Friedrich understands them. To Friedrich's intense and long-continued scrutiny, they indicate, what is next to incredible, but is at length fatally undeniable, That the old TREATY, which we called OF WARSAW, "Treaty for Partitioning Prussia," is still (in spite of all subsequent and superincumbent Treaties to the contrary) vigorously alive underground; that Saxon Bruhl and her Hungarian Majesty, to whom is now added Czarish Majesty, are fixed as ever on cutting down this afflictive, too aspiring King of Prussia to the size of a Brandenburg Elector; busy (in these Menzel Documents) considering how it may be done, especially how the bear-skin may be SHARED;--and that, in short, there lies ahead, inevitable seemingly, and not far off, a Third Silesian War. Which punctually came true. The THIRD SILESIAN WAR--since called SEVEN-YEARS WAR, that proving to be the length of it--is now near. Breaks out, has to break out, August, 1756. The heaviest and direst struggle Friedrich ever had; the greatest of all his Prowesses, Achievements and Endurances in this world. And, on the whole, the last that was very great, or that is likely to be memorable with Posterity. Upon which, accordingly, we must try our utmost to leave some not untrue notion in this place: and that once DONE--Courage, reader! FRIEDRICH IS VISIBLE, IN HOLLAND, TO THE NAKED EYE, FOR SOME MINUTES (June 23d, 1755).
